SD Toolbox 19

A free Substance 3D Designer node library (.sbs) of 15 grayscale utility nodes for procedural texturing: flood fill shortcuts, shape cutting, mask generators (curvature, slope, edge wear, dirt, leaks), blend and transform helpers. Built in 2019, published in 2026 as an archive. MIT license.

The 15 nodes

QuickFlood: Substance Designer flood fill node, input and outputs — QuickFlood: flood fill in one node, with size, gradient and random maps.

Dilate: Substance Designer node that fills the gaps between flood fill cells — Dilate: grows each shape's value into the black gaps.

Mask: Size, Substance Designer size selection mask node — Mask: Size: keeps the largest or smallest shapes.

Mask: Random, Substance Designer random selection mask node — Mask: Random: keeps a random share of the shapes.

Cut Simple: Substance Designer shape cutting node — Cut Simple: cuts every shape along a random line.

Sharp Warp: Substance Designer edge chipping warp node — Sharp Warp: chips straight edges into sharp breaks.

Fillet: Substance Designer rounded corners node — Fillet: rounds the shapes' corners.

Tips: Substance Designer shape tips mask node — Tips: isolates the inner and outer tips of the shapes.

Mask: Lazy, Substance Designer curvature, slope and edge wear masks from a height map — Mask: Lazy: 10 masks from a height map (curvature, slopes, edge wear, dirt, leaks, sun bleach).

Compose: Substance Designer pattern composite node — Compose: keeps a pattern only inside large enough shapes.

Custom Cells: Substance Designer bevelled cells node — Custom Cells: turns a shape pattern into bevelled cells.

Combine: Substance Designer add and subtract blend node — Combine: add or subtract through a mask.

Multiply: Substance Designer multiply blend node — Multiply: multiply through a mask.

Transform: Substance Designer transform 2D node with tiling toggles — Transform: transform 2D with tile X, Y or both.

Lazy Curves: Substance Designer preset contrast curves node — Lazy Curves: 9 preset contrast curves.
